Norwegian Black List

Norwegian Black List is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Norwegian Black List rather than just read about it. In short: The Norwegian Black List (Fremmedartslista) is an overview of alien species in Norway, with ecological risk assessments for some of the species. The Norwegian Black List was first published in 2007 by the Norwegian Biodiversity Information Centre and developed in cooperation with 18 scientific experts from six research institutions.

Key takeaways

Norwegian Black List belongs to biology; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Norwegian Black List to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Norwegian Black List from memory before moving on to harder problems.

Reference excerpt

The Norwegian Black List (Fremmedartslista) is an overview of alien species in Norway, with ecological risk assessments for some of the species. The Norwegian Black List was first published in 2007 by the Norwegian Biodiversity Information Centre and developed in cooperation with 18 scientific experts from six research institutions. The 2007 Norwegian Black List is the first issue, and is compiled as a counterpart to the Norwegian Red List of 2006.

The 2007 Norwegian Black List The 2007 Norwegian Black List contains a total of 2483 species of plants, animals and other organisms, 217 of which are risk assessed. A set of criteria has been developed to ensure a standardised assessment of the ecological consequences of alien species. The assessed species are placed in categories according to the risk they represent.

High risk – 93 species Unknown risk – 83 species Low risk – 41 species Alien species on Svalbard, Bjørnøya and Jan Mayen are not assessed.

Result Among the 93 species which are found to threaten the natural local biodiversity, are bacteria, macroalgae, microalgae, pseudofungi, fungi, mosses, vascular plants, comb jellies, flatworms, roundworms, crustaceans, arachnids, insects, snails, bivalves, tunicates, fishes and mammals. Among the vascular plants with a high risk, are Heracleum tromsoensis (aka Heracleum persicum), sycamore maple (Acer pseudoplatanus) and garden lupin (Lupinus polyphyllus). Among the flatworms; Gyrodactylus salaris, among the crustaceans the red king crab (Paralithodes camtschaticus) and American lobster (Homarus americanus). Five species of mammals are noted as high risk species; West European hedgehog, European rabbit, southern vole, American mink and raccoon.

Worked examples

Example 1 — a first encounter with Norwegian Black List

Start with the simplest possible case. Write down what Norwegian Black List claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Norwegian Black List before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Norwegian Black List ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Norwegian Black List

In research: Norwegian Black List appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Norwegian Black List in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Norwegian Black List is common in secondary-school and first-year university syllabi. It links to neighbouring topics Introduced species, Invasive species, Nature conservation in Norway, so understanding it makes those chapters shorter.
In everyday life: Look for Norwegian Black List outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
